I had forum runner installed on my site. Since a few days i get a load of errors from forumrunner. I am running the latest version. Now i wanted to uninstall the add on, but the strange fenomenon is that its under the options visible, but i cant see it under the installed add ons. So i cant uninstall it.

Is it enough to delete the two tables in the database and delete the two folders?

I see two table's

xf_forumrunner_push_data and xf_forumrunner_push_users

Or should i do more to get rid of this.

Keep in mind that i am no coder. So if i have to execute an SQL statement , that will work, but i cant make the statement if there is a lot to do in SQL.
